To all whom t may concern.'

Be it known that l, FREDERICK L. ATHER- ron, a citizen of the UnitedStates, and a resident of Paterson, in the county of Passaic and Stateof New Jersey, have invented a new and Improved Spooling-Machine, ofwhich the following is la full, clear, and exact description.

The invention relates to "spooling machines used for spooling silk? andother threads on quills :for use in loom shuttles.

The objectof the invention isto provide a nenT and improved spcolingmachine arranged to permit of running `the quill or spool-carryingspindlerr at a high rate of speed to Wind the thread on the quill orspool With a view to prevent 'the ythread from slonghing when the quillcr spool is used' in a loom shuttle, to insure Winding of the thread onthe quill or spool with uniform tension and to automaticallystop thespindle as soon as the quill or spool is filled with the desired amountof thread.'y

ln order to accomplish the desired result use is made of a revolublespindle adapted to carry a quill, spool, bobbin or the like and a threaddelivery device for delivering the thread to the said quill and having areciprocating increment in the direction of Vthe length of the spindle,the said thread delivery d rice being provided with feed` mechanism forimparting a bodily in'ovement to the delivery device, the said feedingmechanism receiving periodical movement by contact with `the thread`passing from the delivery device onto the quill., Use is further madeof means for imparting an irregular reciprocatingmovement to thedelivery device and to the feeding mechanismwith a rien* to Wind thethreads in such a marmer onto thequill yto prevent slonghing of thethread when the filled quillis used in a loom shuttle..

l practical embodiment of is -represented in the accompanying drawe ingsforming a part of this specification, in which similar characters ofLreference indicate corresponding parts inall the views.

The spooling machine, as shown in the drawings, is provided with aseries of twenty vertically-disposed spindles C, ten oneach side ofthemachine,.each spindle C being attached to a pulley C" (see Fig. 7), andthe several pulleys C are adapted t be driven by frictional contact witha single endless belt lD passing around end pulleys E, E

' yand Vover a series of intermediate pulleys E2 (see Figs. 1 and 2).The end pulley E is securedon the ,upper end of a vertically-disposedsh'aft E3 journaled in a bearing E1 attached toone end of the main frameA, and on the said shaft E3 is secureda pulley F `around which passes abelt F, the runs of which pass over guide pulleys F2 to yhn'ally'passaround a pulley F3 secured on the main shaft B so that when the latteris running a rotary motion istransmitted by f the means just describedto the shaft E3 and the pulley Eto cause the belt D to travelr in thedirection ofthe arrow a indicated in Fig. 2.' Each of the guide pulleysF2 above mentioned is mounted to rotate loosely on a transverse rod F4adjustably secured to an arm F5 adjustably securedm a bearing F6,

, and the said bearingFG is adjustably secured in a bearing F7 attachedto the main frame A. By the arrangement described the pulleys F2 can beadjusted so as to give the desired tension to the belt F and to properlyguide the runs of the belt F from the pulley Fto thepulley F3. Theintermediate pulleys E2 are journaled in suitable bearings E5 attachedto the main frame A, and the end pulley E is jeurnaled in a 'bearing E5(see Figs. 17 and 18) mounted to slide in a suitable guideway E7arranged on the main frame A. The bearino' E is ressed on b i tensionrto the belt D;

The spooling devices for the several spindles C are alike inconstruction and hence it suliices to describe but one in detail. The

f thread H to be wound on a quill'H or like device held on the spindleyC unwinds from a spool H2 held loosely on a` spool holder H3 attachedto the upper portion of the main frame A, as plainly indicated in Fig.4.

The thread `H after unwinding fromr theV `spool-H2 passes through aguide H4 held on the main framek A, and then the thread J2 is adjustablysecured by a set screw J3 an.

arm J 4 engaging an annular groove J5 in a collar J6 formed on a sleeveJ7 adjustably secured in a bushing K of a feed member K in the form ofan inverted frustum of a cone. The sleeve J 7 is secured in the bushingK by a set screw K2 and through the said i sleeve J7 extends loosely ascrew rod K3 adapted topbe engaged by ahalf nut K formed on a lever K5pivoted on the top of the bushing K, as plainly indicated in Fig. 9 (seealso Fig. 14) .j The lever K5 is pressed on by a spring K6 Vto normallyhold the half nut K4 in engagement with the screw rod K3. Y The sleeveJ7 is provided near its upper end with a cut-out portion J 5 toaccommodate the lever K5 and Yits half nut K4, one side wall of thecut-out'portion J 2 forming a stop for the said lever K5, as will bereadily understood by reference to Fig. 9. Now on adjusting the sleeve`J 7 in the bushing'K after loosening the set screw K2 ythe LhalflnutvKl2 can be adjusted to properly engage the threads ofthe screw rodK3 without causing undue friction. After the desired adjustment is madethe set screw K2 is screwed up to'fasten the sleeve J7 in place.

The screw rod K3 is irregularly reciprocated in the direction of itslength kby an actuating mechanism presently to be described in detail.The lower non-threaded portion K7 ofthe screw rod K3 is pivotally armsL3 extending transversely from a rock shaft L4E extending lengthwise ofthe machine and journaled in suitable bearings L5v held on the mainframe A. It is understood that arIpIlsL3 extend from the rock shaft L4in opposite directions to connect by the links L2 with the y two rods Lon opposite sides of the machine, as will be readily understood byreference tok Fig. 4. The rock shaft L4 isprovided with @dependingarm'L6 connected with a transversely-extending slide N carrying afriction roller N engaging a face cam O (see Fi-gs. 4, 5, `6 and 10)secured on a sleeve O mounted to turn and to slide onatransversely-extending guideway or rod A2 supported on brackets A3attached to 'or forming part of the main frame A. On the sleeve O issecured a worm `O2 in mesh with a worm wheel O3 secured on the mainshafty B so that when the machine is running and the shaft B is rotatedthen a rotary motion is transmitted by the worm wheel O3 and the worm O2to the sleeve O and its cam O for the latter to impart a reciprocatingmotion to the slide N. The slide N is pressed on by a spring N2 tonormally hold the friction roller N in Contact with the face of the camO. The slide N is provided with lengthwise-extending slots N3 (see Figs.l() and l1) through which extend guide blocks N4 held on bolts N5attached to a cross bar A* forming part of the main frame A. rlhe slideN is also provided with a pin N6 carrying a block NT extending yinto aslot L7 formed in the lower end of the depending arm L6 sol that when asliding motion is given to the slide N by the action of the cam O andthe friction roller i then a transverse swinging motion is given to thearm LG to rock the shaft L4. The rocking motion given to the shaft L4 istransmitted by the arms L3, links L2, rods L and heads L to the screwrods K3 to reciprocate the same, it being understood that when themachine is running the screw rods K3 on the opposite sides of themachine reciprocate up and down alternately in opposite directions, thatis, when the screw rods on one side of the machine move upward the screwrods on the other side of the machine move downward and vice versa.

The mechanism just described would impart a regular reciprocating motionto each of the screw rods K3, but in orderrto wind the thread H on thequill H in such a Inan-` ner that the thread is prevented fromsloughing, an irregular reciprocating' kmotion is given to the screwrods, and forthis purpose the following arrangement is made: 0n thesleeve O is secured a pinion P in mesh with a gear wheel P secured on acountershaft P2 journaled in suitable bearings arranged on thebracketsA3 (see Figs; 4, 5 and 6). On the counter-shaft P2 is secured agear wheel P3 in mesh with a gear wheel P4 mounted to rotate loosely onthe rod A27 and on the face of this gear wheel P1 are secured camsections P5, yPG by the use of bolts P7 held on the gear wheel P4. Thecam sections P3, P6 form an adjustable cam and the outer face of thesection Ps is engaged by a friction roller O4 journaled on a disk C)5secured on the sleeve O adjacent the worm O2, as plainly shown in Figs.5l and 6. When the machine is running and a rotary motion is given tothesleeve Oas previously explained then the gear wheels P, P rotate thecounter-shaft P2 andy the rotary motion of the latter is transmitted bythe gear wheels P3, P4 to the cam formed of the sections P57 P3, so thata reciprocatingk motion is. given by the frictionY roller 0f* and thedisk O5 to the sleeve O whichfcarriesy the cam O whereby the latter isbodily shifted in the direction of its axis. As the friction roller N ofthe slide N is'held in contact with the face of the cam O by the actionof the spring N2 it is evident that the friction roller 0f is likewiseheld in contact with the face of the cam section P6 owing to the factthat the disk O5 carrying the said friction roller O4 is attached to thesleeve O which in turn carries the cam O. The outer face of the camsection PG is irregular. and thecam sections P5, P6 are approximatelywedge-shaped, as indicated in Fig. 20, and the bolts P7 pass throughsegmental slots P8 in the cam section P5 to allow of shifting the camsection P5 on the said bolts relative to the cam section P6 to changethe latter relative to the cam O with a view to give more or less throwto the sleeve O and the cam O in the direction of the axis thereof. rPhecam section PiS is preferably provided with a second set of segmentalgrooves P9 concentric to the grooves P3 and adapted to be engaged by thebolts P7 to allow of varying the throw yof the cam section P6 still morewhenever it is. desired to do so, the cam grooves P3 being intermediatethe ends of the cam grooves P8, as indicated in Fig. 2l. A spring O6 ispreferably coiled on the rod A2 gear wheel P (see Figs. 5 and G) toassist the spring N2 in holding the frictional roller O4 in `engagementwith the face of the cam section PG. The spring 0 bears against theadjacent bracket A3 previously mentioned. It is'understood that by thearrangement described the cam O besides its regular rotary motionreceives a ybodily irregular reciproeating motion in the direction ofits axis and consequently an irregular reciprocating motion is given tothe slide N and this motion of the slide N is transmitted by the arm L6to the rock shaft L4 so that the latter rocks irregularly andconsequently more or less up and down movement is given to the screwrods K3.

In order to prevent backlash of the gearing abovesdescribed'thccounter-shaft P2 is provided with a brake wheel Q engaged by a brakeband Q secured at one end to the main frame A and supporting at itsother end, ra weight Q2 to brake the wheel Q, with suiiicient force toprevent backlash in the gear wheels P, P, P3 P4 and the worm O2 and itsworm wheel O3. to insure an' easy and noiseless running of the machine.One end of the rod A2 is hollow and connected with a pipe A5 forintroducing a lubricant into the hollow end of the rod A2 to conduct thelubricant by way of apertures to the sleeve O1 to lubricate the same, aswill'be readily understood by reference toFig.

Each spindle C s provided with a coniment (see Fig. 7). The arm Sisprovided cal portion 'C2 (see Fig. 7) driven" into a correspondingborein the end of the pulley C, and the said spindle C isV provided with 'ashank C5 extending downward from the conical portion C2 and engaging arecess R 1n a pm R on which the pulley C is mounts ed to rotate loosely.The pin R is provided with'a collar R2 seated on top of an arm S andheld against turning thereon by a ylug R2 engaging a corresponding notchinV the arm S (see Fig. 7). Aspring R4 iscoiled on the lower portion ofthe pin R and rests with its` upper end on the under side of the armSwhile the lower end of the said spring presses against a collar Rscrewing on the lower threaded portion of the pin klt so that the collarR2 is held rmly in posiz tion on the arm S. VThe collar R2 is providedwith anV angular Vretaining pin R5 en.- gagmg-the bottom flange C4 ofthe pulley C to hold the latter against upward movewith a pivot pin S(see Figs. and 16) mounted to turn in a bushing S2held on -f the spindlerailAG forming part of the main it the 'spindle C to move the pulleyv C"out of engagement with the travelingbelt D;

In order to hold the pulley C in contact.

with the belt D use is made of a bolt VT mounted to slide `transverselyin a suitable bearingy T arranged on the spindle rail :A5

" (see Figs. 2, 3, l, 7 and 15).- lThe outer Vend of'the bolt' T isprovided with a suitable knob T2 land the inner end of the said bolt Tengages the free end of the arm S sothat' when the knob T2 ispushedinward an inward swinging motionis given tothe arm.

S against the tension of the spring S3 to move the pulley C infrictional Contact with the belt D. Then this takesplace a rot-arymotion is transmitted by the 'belt D to the pulley yCto rotate thespindle Gand the quillA H held thereon. The'bolt T is held againstturning in its bearing T by a U-shaped rod T3Y extending transverselythrough the bolt and resting with its ends on the rail A (see Fig.Y 13).The bolt T is provided with an annular groove T4 adapted to be engagedby a lever T5 fulerumed at TG on the inner edge of the bearing' T (seeFigs. 3 and with a handle TT under the control of the operator, and thesaid lever is also provided with an angular .transversely-extending armrllhe lever T5 is providedV T8 extending into the path of a vcollar Uadjustably secured by a set screw U on a vertically-disposed rod U2secured at itsupperend to the arm J4 (see Fig. 7) and engaging a bracketU3 attached to the lower end K7 of the screw rod K3 A spring U4 iscoiled on the lower end of the rod U2 and its upper end is attached tothe bracket U3 while the lower end ofthe spring U4 is attached to acollar U5 adj ustablysecured by a vset screw U5 on'the lower end of therod U2. VThe spring U4 is a pull spring and is intendedv to slightlyoverbalance the thread vdelivery device and its feed mechanism,consisting essentially of the feed member K and the parts supportedthereby. By this arrangement thev feed member K rotates freely on theVscrew rod K3 so that a light touch of the peripheral face of the feedmember Kfonfthe portion of the thread wound upon the quill H vat thetime is sufficient to imparty alrotary motion to the feed' member K.They peripheral face of the feed member K touches the thread at thetimethe feed member'K is at the end of its downward stroke so that anintermittent rotary motion is given to the feed member K at every fullstroke of the screw rod K3, the feed member K moving bodily up and downwith the said screw rod. By adjusting the collar U5 on the rod'U2 Vthetension ofthe spring U4 can be regulated to overbalance the threaddelivery device and Aits .feed mechanism, as y above explained. Thecollar U is-adjustable on the rod U2 so1that the collar engages theangular arm TS of the lever T5 sooner'or later according to the heightof the thread to be wound on the quill H. It is understood that the rod.U2 moves upward with the arm. J4 and when the collar U imparts anVupward swi-nging movement to the lever T5 then the latter disengagesVthe annular groove T4 and thus unlocks the bolt T to allow'the spring S3to swing the arm S outward with a yview to'disengage the npulley Cfromthe` belt D. YWhen this takes place the rotation of the spindleCceases and the quill Y H has been filled with the desired amount ofthread H andthe filled quill can now be removed from the spindle C. f

Each of the'tension spools I, I is provided with a lspiral groove l2 onwhich the thread His wound a number of times according to the nature ofthe thread, sotha*V the convolutions of the wound portions ofrVthethread Vare separate oneffrom the other.

The tension spool I is provided with a ring I3 adjustably fastened by aset screw I4 to a Vsleeve l5 mounted to slide on the guide rod Apreviously mentioned. The sleeve I5 is provided with a key l5 engaging akeyway I7 formed in the guide rod A to hold,

the tension spool'I against turning on the guide rod A. The bottom ofthesleeve I5 rests on Ltop of a kspring 18 coiled on theV y,incassa guiderod A and resting with its bottom on a bracket T3 secured on the guiderod and to which bracket T3 the other lower tension spool I is secured.Thus by the arrangement described the upper tension spool I is free toyield in a vertical direction to take up any slack that may eXistbetween the tension spool T and the guide H4. It is understood that bothtension spools I, l are held against rotation and by winding the threada number of times in thegrooves f3 it is evident that the desiredtension is obtained to prevent any slack in the thread between thetension spool l and the eye J. The machine is provided at each side witha trough V for the reception of spools and the like, and the sides ofthe machine are alsov provided with guard rails W and a guard rail VJextends lengthwise above the pulleys E, E and E3.

The operation is as follows: The attendant of the machine places a quillH onto the spindle C at the time the arm S is in outermost position andthe spindle 1sA at rest. The attendant now presses the knob T3 inward toimpart an inward swinging motion to the arm S with a view to engage thepulley C with the running belt D to cause the spindle C to rotate. Whenthe knob T3 is pushed inward the lever T5 drops Minto the annular grooveT* and thus locks the bolt T and the armv S against outward mcvement.The half nut KAL at the beginning of the operation engages the screw rodK3 at such a point that the lower end of the feed member K and the eye Jare about opposite the bottom of the quill H at kthe time the screw rodK3 is at the lower end 0f its down stroke. The attendant attaches theterminal of the thread H in the usual manner to the quill H .so that therotating quill winds up the thread and as the screw rod K3 reciprocatesin an up and `down direction and with it the eye J it is evident thatthe thread H is fed onto the quill with the convolutions one alongsidethe other. At the beginning of the operation the upper edge of the feedmember K is in close proximity or touches the upper portion of the quillH while the lower or smaller end kof the feed member K is a distanceaway from` the quill H, but after some of the thread Hy has been woundon the lower portion of the quillv H then the lower end of the feed..member K touches the thread at the timek the feed member K moves into'lowermost position.

The contact of thefeed member K with the thread is but for an instantbut suiiicientto give a slight turning motiony to kthe feed member Kwhei'eby the .half nut K4 is caused to screw en the screw rod K3 thusmoving the feed member ll" and the eye J in an upward direction togetherwith the rod U3 and its tripping col-lar U; This operation is repeatedat every down stroke from start to finish.

of the screw rod K3 and consequently after each fullstroke of the screwrod K3 the delivery device and its feeding mechanism have been raisedapproximately the thickness 0f the thread H wound on the quill H at thetime. In the course of the further running of the machine the thread His wound on the quill H and the lower portion of the wound thread is inthe form of an inverted frustum of a cone of a height corresponding tothe throw of the screw rod K3, while the middle portion of the filledquill H is cylindrical and the upper portion is again tapering, and whenthe quill has been filled to the desired height then the collar Uengages the arm T3 and finally swings the lever T5 upward thus unlocking,the bolt T and allowing the arm S to swing outward by the action of thespring S3. The rotationv of the spindle C now ceases and the thread H isbroken close to the filled quill H and the latter is removed from thespindle C and replaced by an empty quill, after which the operator takeshold of the lever K5r and swings the same outward to `disengage the halfnut K'3 from the screw rod K3 to allow the feed member K and the partssupported thereby to drop back into lowermost position, `after which theoperator releases the lever K5 to allow the spring K3 to return thelever K5 with a view to rekengage the half nut K4r with the screw rod`K3. The above described operation is then repeated, ythat is, theoperator presses the knob T3 inward to rengage the pulley C with thebelt D, after which the operator connects thev end of the thread H withthek shuttle. lBy counterbalancing the feed member K and the threaddelivery device by the use of the spring U as previously mentioned, thefeed member K is not liable to injure the thread during the time of thecontact between the peripheral face of the feed membery K and thethread, as above explained. By using the tension spools T and I auniform tension is given to the thread H to insure a uniform spooling ofthe thread on the quill so that the spooling is of the same hardness oruniformity of winding It is understood that by the arrangement describedthev spindle C can be run at a very high rate of speed (from 4,000to5,000) and as thespooling is automatic it requiresno highly skilledattendant for running the machine.

n the foregoing use is madeof theterm quill but it is evidentthat thepart referred to may be in the nature of a spool,

Vbobbin or similar device.

Having thus described my invention, I
